The embodiments described below are merely examples of the embodiments of the present invention, and the present invention is not limited to these embodiments. In the drawings referred to in the present embodiment, the same reference numerals or similar reference numerals are given to the same portions or portions having the same functions, and redundant description thereof may be omitted. For convenience of explanation, the dimensional ratios in the drawings may be different from the actual ratios, and some of the components may be omitted from the drawings.
(one embodiment)
The structure of the semiconductor device 1 according to one embodiment will be described with reference to fig. 1(a) to (D). Fig. 1(a) to (D) are diagrams illustrating the structure of the semiconductor device 1. Fig. 1(a) is a bottom view of the semiconductor device 1. Fig. 1(B) is a plan view of the semiconductor device 1. FIG. 1(C) is a sectional view taken along line A-A of FIG. 1 (B). FIG. 1(D) is a sectional view taken along line B-B of FIG. 1 (B). In the present embodiment, the direction from the upper surface to the lower surface of the semiconductor device 1 is represented by the Z direction, and the directions orthogonal to the Z direction are represented by the X direction and the Y direction.
As shown in fig. 1(a) to (D), the semiconductor device 1 includes four leads 2, an island 3, a semiconductor element 4, a bonding wire 5, and a resin package 6. The semiconductor device 1 is a rectangular parallelepiped. The size of the semiconductor device 1 is not particularly limited. The broken line 50 in fig. 1(a) indicates the lead 50 of the comparative example described later using fig. 3(a) to (D), and the broken line 60 indicates an example of forming an island 60 of the comparative example described later. Fig. 1(B) is a plan view of the resin package 6. Therefore, the upper surface of the semiconductor device 1 is actually covered with the resin package 6. A broken line 200 in fig. 1(B) indicates the lead 2 shown in fig. 1(a), and a broken line 300 indicates the lower surface pattern of the island 3.
Fig. 2 is a diagram showing an example of arrangement of a plurality of semiconductor devices 1 in a resin package 400.
As shown in fig. 2, a plurality of semiconductor devices 1 are arranged in the resin package 400. The lead frame 500 of the resin sealing body 400 is cut out together with the resin, thereby producing the semiconductor device 1.
The material of the lead 2 and the island 3 is not particularly limited, and is Cu, for example. For example, the lead 2 and the island 3 are formed of the same metal plate, and have the same maximum thickness. In the present embodiment, the island 3 corresponds to the first terminal, the lead 2 corresponds to the second terminal, the bonding wire 5 corresponds to the conductive wire, and the resin package 6 corresponds to the inner package.
The four leads 2 are separated from the island 3 and the semiconductor element 4. That is, in the present embodiment, four leads 2 are disposed separately from each other with an island 3 and a semiconductor element 4 interposed therebetween. In this way, the four leads 2 are arranged at the 4-corner of the resin package 6. In this case, as shown by an arrow W2 in fig. 1(a), the side surface of the semiconductor device 1 may have an edge portion in which the lead 2 is covered with the resin package 6.
Each lead 2 has a non-etched portion exposed from the bottom surface of the resin package 6, and a terminal half-etched portion 2a that is covered with the resin package 6 on the lower surface side and has a smaller thickness than the non-etched portion. The terminal half-etched portion 2a extends a predetermined length (width) from the non-etched portion toward the island 3 and the adjacent lead 2. The terminal half-etched portion 2a can be formed by, for example, chemical etching or flattening. The material of the resin package 6 enters and covers the terminal half-etched portion 2 a.
In this specification, the lower surfaces and shapes of the lead 2 and the island 3 refer to the non-etched portion exposed from the bottom surface of the resin package 6 and the shape thereof. The shape of the lead 2 and the island 3 or the shape of the upper surface refers to a shape in which the non-etched portion and the half-etched portion are integrated in a plan view. The non-etched portions and half-etched portions of the leads 2 and the islands 3 are smoothly continuous on the upper surface. The upper surfaces of the lead 2 and the island 3 have a shape in which the width of the lead 2 and the lower surface of the island 3 is increased by half etching.
The lower surface of each lead 2 is exposed on the bottom surface of the resin package 6 except for the terminal half-etched portion 2a, and functions as an external terminal connected to a wiring board (not shown).
The lower surface of the lead 2 has a pentagonal shape, and has sides 20 and 22 parallel to one pair of opposing sides of the semiconductor element 4, and sides 21 and 23 parallel to the other pair of opposing sides of the semiconductor element 4. Each lead 2 further has a side 24 which is not parallel to any one side of the semiconductor element 4, for example, inclined by 45 degrees. Side 23 is shorter than side 20.
The upper surface of the lead 2 is pentagonal in shape, and has sides 120 and 122 parallel to one set of opposing sides of the semiconductor element 4, and sides 121 and 123 parallel to the other set of opposing sides of the semiconductor element 4. Each lead 2 further has a side 124 which is not parallel to any one side of the semiconductor element 4, for example, inclined by 45 degrees. Edge 123 is shorter than edge 120.
The lower surface of the island 3 is substantially diamond shaped. The lower surface of the island 3 of the present embodiment has a shape obtained by rounding the corners of a diamond, for example, by cutting. The sides of the rhomboid shape in the lower surface of the island 3 are not parallel to the sides of the resin package 6. In other words, the lower surface of the island 3 has a shape having 2 sets of opposite sides parallel to each other. The opposite sides of the group 2 of islands 3 are not parallel to any one side of the resin package 6. The length of the lower surface of the island 3 in the X direction is longer than the length in the Y direction. The upper surface of the island 3 is substantially rhombic except for the portions 30a and 30b, and the substantially rhombic shape can be said to be the same as the lower surface of the island 3.
The lower surface of the island 3 is exposed at the bottom surface of the resin package 6. An island half-etched portion 3a is formed on a side surface of the island 3 facing the lead 2. The material of the resin package 6 enters the island half-etched portion 3 a. In other words, each lead 2 has a non-etched portion exposed from the bottom surface of the resin package 6, and an island half-etched portion 2a that is covered with the resin package on the lower surface side and has a smaller thickness than the non-etched portion. The island half-etched portion 2a extends from the non-etched portion in the XY plane by a predetermined length (width). This can improve the bonding strength between the island 3 and the resin package 6. The island half-etched portions 3a can be formed by, for example, chemical etching or flattening.
The island half-etched portion 3a of the island 3 has arm portions 30a and 30b extending and protruding in the X direction. As shown in fig. 2, the arm portions 30a, 30b are connected to the lead frame 500, thereby preventing the island 3 from falling off from the lead frame 500. In the present embodiment, as shown in fig. 2, the regions 30a and 30b of the island 3 connected to the adjacent lead frame 500 before cutting are referred to as a boom portion or a hanger pin. The plurality of leads 2 are disposed at respective end portions of 2 sides of the resin package 6 extending in the X direction when viewed in plan in the Z direction. The two spaces a2 formed between the ends adjacent in the Y direction include the boom portions 30a, 30 b.
On the other hand, the island 3 is separated from 2 sides extending in the X direction when viewed in plan in the Z direction. In other words, the island 3 is separated from the side surface of the resin package 6 parallel to the Z direction and the X direction. Therefore, the region B2 in which 2 sides of the island 3 and the resin package 6 extending in the X direction do not contact each other can be provided when viewed in plan in the Z direction.
In fig. 1(B), in other words, when viewed in plan in the Z direction, the points at which the arm portions 30a and 30B are in contact with the opposing 2 sides of the resin package 6 are at least 2 points apart. As shown in fig. 1(a), the midpoint of the island 3 is located between 2 points of the boom portions 30a and 30b in a plan view.
The semiconductor element 4 (semiconductor chip) has a rectangular shape. The semiconductor element 4 has a back surface bonded to the island 3 via an adhesive in a state where the front surface (device formation surface) on which the functional element is formed is directed upward. The bonding material is, for example, a non-conductive bonding material, but a conductive bonding material can also be used.
The angle formed by the side of the semiconductor element 4 and the side of the resin package 6 is 20 degrees or less. It is more preferable that the sides of the semiconductor element and the sides of the resin package 6 are parallel. As shown in fig. 1(B), when viewed in plan in the Z direction, the corners of the semiconductor element 4 are not included between two leads 2 adjacent in the X direction. The corners of the semiconductor element 4 are included between two leads 2 adjacent in the Y direction when viewed in plan in the Z direction.
On the surface of the semiconductor element 4, pads 4a corresponding to the respective leads 2 are formed. One end of the bonding wire 5 is bonded to each pad 4 a. The other end of the bonding wire 5 is bonded to the upper surface of each lead 2. Thereby, the semiconductor element 4 is electrically connected to the lead 2 via the bonding wire 5.
The structure of comparative example 1a of semiconductor device 1 according to one embodiment will be described with reference to fig. 3(a) to (D). Fig. 3(a) to (D) are diagrams illustrating the structure of the semiconductor device 1 a. Fig. 3(a) is a bottom view of the semiconductor device 1 a. Fig. 3(B) is a plan view of the semiconductor device 1 a. Fig. 3(C) is a sectional view taken along a-a of fig. 3 (B). Fig. 3(D) is a sectional view taken along B-B of fig. 3 (B).
As shown in fig. 3(a) to (D), the semiconductor device 1a includes four leads 50, an island 60, a semiconductor element 4, a bonding wire 5, and a resin package 6. The semiconductor device 1a is a rectangular parallelepiped. The semiconductor device 1a includes a semiconductor element 4 and a resin package 6 included in the semiconductor device 1. Fig. 3(B) is a plan view of the resin package 6. Therefore, the upper surface of the semiconductor device 1 is actually covered with the resin package 6. The broken line 200a in fig. 3(B) represents the lead 50 shown in fig. 3 (a). The semiconductor element 4 has, for example, the same shape as the lower surface pattern of the island 60, and is provided directly above the lower surface pattern of the island 60.
As shown in fig. 3(a), 1 side of each lead 50 and 4 sides of the island 60 are arranged on the lower surface so as to be inclined at a predetermined angle, for example, at 45 degrees, with respect to the side of the resin package 6. That is, on the lower surface, 1 side of each lead 50 is arranged in parallel with any one side of the island 60 with a space.
In the semiconductor device 1a of the comparative example, the side of the semiconductor element 4 was arranged at 45 degrees with respect to the side of the resin package 6. Thus, the semiconductor device 1a is arranged such that the upper surface of the lead 50 provided at the 4-corner of the package 6 is separated from the lower surface of the semiconductor element 4 while taking the areas of the island 60 and the lead 50 large.
In manufacturing the semiconductor device 1a of the comparative example, it is necessary to perform a rotation operation in which the side of the semiconductor element 4 is rotated by 45 degrees with respect to the side of the resin package 6. In general, the alignment of the semiconductor element 4 is less accurate in the case of the rotation operation. In the comparative example, one corner of the semiconductor element 4 was cut at 45 degrees, and the edge formed by the cutting was aligned in the X direction, thereby improving the accuracy of alignment during the rotation operation. Further, by obtaining the area of the island 60 to be large, the alignment margin of the semiconductor element 4 is obtained to be large. The apex of the rectangular semiconductor element 4 is close to the side of the resin package 6.
Further, the lead 50 has a triangular shape. The lower surface of the island 60 of the present embodiment has a shape obtained by rounding the corners of a triangle, for example, by cutting. The arm portions of the islands 60 extend and protrude toward the sides of the resin package 6. Since the island 3 has a large area, the possibility of the island 60 being close to each lead 50 and short-circuited is increased in both the X direction and the Y direction.
The arm portions of the comparative example extend in the X direction and the Y direction, and are prevented from shifting and twisting when the island 60 is connected to the lead frame.
Since the semiconductor device 1 of example 1 is not provided with the arm portion extending in the Y direction, the region B2 can be acquired largely. This makes it possible to widely obtain the gap between the side 121 of the lead 2 and the island 3 in the X direction. Therefore, even when the size is further reduced, it is possible to suppress short-circuiting between the lead 2 and the island 3, which may occur due to metal dragging or the like when the lead frame is cut along the line extending in the X direction.
The island 3 of the semiconductor device 1 has a substantially rhombic shape having a length in the Y direction smaller than that in the X direction. Therefore, the distance between the island 3 and the side 24 of each lead 2 increases from the end of the side surface of the resin package 6 toward the midpoint in the X direction.
The length of the lead 2 in the Y direction is shorter than the length in the X direction. Therefore, even in the vicinity of the end in the X direction of the side surface of the resin package 6, the distance between the island 3 and the side 24 of each lead 2 can be obtained largely. Further, the distance between side 22 of each lead 2 and each of arms 30a and 30b and the distance between side 22 of each lead 2 and the rear surface of semiconductor element 4 can be obtained widely.
Therefore, the possibility of short-circuiting the lead 2 and the island 3 and the like is further reduced. That is, the gap is further increased. This enables further miniaturization of the semiconductor device 1.
The arm portions 30a and 30b are exposed from the resin package 6 at least at 2 points separated in the Y direction and connected to the lead frame. Since the boom portions 30a and 30b are divided into 2, compared with 1 thick boom portion, the metal cutting area during dicing can be reduced, stress concentration can be alleviated, and the quality of packaging can be improved. Also, in the case of using the cutting blade, clogging of the cutting blade can be prevented.
In the semiconductor device 1, the angle formed by the side of the semiconductor element 4 and the side of the resin package 6 is 20 degrees or less or parallel. Therefore, the operation of making the semiconductor element 4 meet 45 degrees with respect to the side of the resin package 6 as in the comparative example is not necessary, and the productivity of the semiconductor device 1 is further improved. In other words, by further shortening the side 23 of the lead 2, the semiconductor device 1 can be arranged without making the side of the semiconductor element 4 at 45 degrees with respect to the side of the resin package 6.
Further, in the semiconductor element 1, since the distance between the semiconductor element 4 and the side surface of the resin package 6 can be obtained largely, the stress applied to the semiconductor element 4 when the resin package 6 is cut can be reduced.
As described above, according to the present embodiment, the plurality of leads 2 are arranged at the 4-angle of the resin package 6, and the angle formed by the side of the semiconductor element 4 and the side of the resin package 6 is 20 degrees or less. This makes the distance between the apex of the semiconductor element 4 and the side of the resin package 6 longer, and the possibility of short-circuiting between the island 3 and each lead 2 is further suppressed, so that the semiconductor device can be further miniaturized, and the operation of making the semiconductor element 4 meet 45 degrees with respect to the side of the resin package 6 is not required, thereby further improving the productivity of the semiconductor device 1.
The island half-etched portion 3a of the island 3 has arm portions 30a and 30b extending in the X direction and exposed from the side surface of the resin package 6 when viewed in plan in the Z direction, and is formed separately from the side surface of the resin package 6 in the Y direction. This prevents the island 3 from falling off the lead frame, and provides the region B2 where the island 3 does not contact the side surface of the resin package 6. In this way, the semiconductor device 1 can be further miniaturized, and the productivity of the semiconductor device 1 can be further improved.
(modification of the first embodiment)
The semiconductor device 1b according to the modification of the embodiment is different from the semiconductor device 1 according to the modification of the embodiment in that the semiconductor device 1b is disposed so that the arm portions 32 and 34 of the island 3 are offset in the opposite left and right directions from the midpoint of the opposing sides of the resin package 6.

Fig. 4(B) is a plan view of the semiconductor device 1B. Fig. 4(C) is a sectional view taken along a-a of fig. 4 (B). Fig. 4(D) is a sectional view taken along B-B of fig. 4 (B). The arm portions 32 and 34 of the island 3 are arranged offset in the opposite left-right direction from the midpoint of the opposing sides of the resin package 6. Torsion can be suppressed by the boom portions 32, 34.
Although the semiconductor device 1 has been described in the present specification as having the semiconductor element 4 mounted on the lead frame, it may be of a so-called lead-free type having the semiconductor element 4 mounted on a substrate or the like.
